[citation][nom]bystander[/nom]What makes the gk104 mid-ranged? I'm confused on this. It's their top in gaming graphics chip, I'm not sure what makes that mid-ranged.That said, I am hoping for the best, as I do want to upgrade my 470's and maintain 3D vision.[/citation]
gf104 and gf114 were mid range GPU's. So it's based on GPU naming convention, but also die size (roughly 300mm^2), TDP, and memory interface (since the Geforce 8 era, Nvidia's mid range GPU's have used 256-bit interfaces). All of these attributes are indicative of a mid-range GPU. There's also the fact that Nvidia is working on a higher-end Kepler derivative, with a wider memory interface and larger die size (gk110).
I don't think anyone's trying to argue that the GTX680 is mid-range, because it obviously isn't. It's priced as a high-end card. But the GPU is almost without a doubt a mid-range offering, and I wouldn't be surprised to see the GTX680 drop to mid-range price points at some point in the future.
